Features of Smart Battery Isolator
1. Dual Battery Management: The isolator allows for the simultaneous charging of two separate batteries, typically a primary starting battery and a secondary deep-cycle or auxiliary battery.
2. Compact Design: The dual battery isolator is usually designed to be compact and space-efficient, allowing for easy installation in vehicles or boats with limited space.
3. LED Screen: The isolator is equipped with an LED screen that displays important information about the battery systems.
4. Priority Charging: The isolator typically has a priority charging feature, which ensures that the primary starting battery receives the first and highest priority for charging.
5. Smart Technology: The "smart" aspect of the isolator refers to its intelligent charging algorithm, which monitors the battery conditions and adjusts the charging process accordingly.
Operating Manual:
1.Manual and auto modes
a. Long press the "Select" button for 3 seconds -the blue(LED) indicator will be ON, the manual mode is on.
b. Long press the "Select" button for 3 seconds -the blue(LED) indicator will be OFF, the auto mode is on.
2. Manual state use function The blue indicator light is ON, press the button each time, youcan complete the circuit connection and disconnectionThe circuit switched on the red indicator, the voltmeter lights up at the same time. The circuit disconnect red indicator light, the voltmeter goesout at the same time.
3.Automatic state use function a. When the input voltage exceeds 13.3V, the circuit will beconnected automatically. The voltmeter and red (LED) indicator will also be ON b.When the input voltage drops to 12.7V, the circuit will bedisconnected automatically. The voltmeter and red (LED)indicator will also be OFF.
4.High & low pressure protection a. When the input voltage reaches lower than 11V, the circuit will be disconnected automatically to protect the main batteryfrom over discharging. b.When the input voltage reaches more than 17V, the circuitwill be disconnected automatically to protect the second battery from over discharging.
5.Voltmeter display
a. If two batteries are connected, then the voltage displayed on the voltmeter is the battery tnat has higher voltage.
b.Only connect the battery tnat you would like test the voltage and disconnect the other battery.
c. When the voltmeter is not wurking, press the button once,the voltmeter will display the value for 2 seconds.
